1' o all whom 't may concern:

Be it known that we, J. A. HARTUDEDand Il. l lENGEMBRE, of Pittsburg, inthe county ot' Allegheny and State ot' Pcnnsylvania, have invented a newand Improved Uondenser; and we lo hereby declare that the following is afull, clear, and exact description' thereot', which will enable othersskilled in the art to make and use the same reference being had to theaccompaying drawings, foring part of this specification, in which- Figure 1 represents a longitudinal vertical section of our invention, theline .r nc, Fig. 2, indicatiug the plane ot' section. Fig. 2 is asectional, plan, or top view ot' the same, the plane of section beingindicated by the -line ?I y, 4

Similar letters of reference indicate like parts.

This invention consists in the arrangement in the interier of acomlenser of' two or more conieal pipes placed one over the other so as'jectoy or, more properly speaking, the expeller, thus obtained, isregulated by a loat which opens oreloses the steam or compresscd, airsupply pipe.

A represents a coudcnser, constructcd ot' cast-iron plates or othersuitable material in any convenient form and size. This eon-- densercommunicates with the exhaust port or ports ot' a stean-cylinder bymeans ot' a pipe, l, and the exhaust steam, on arriving in thecondenser, neets a sprayof cold water ijected through the nose G fromthe supply: pipe D, or in any suitable manner. The at mosphoric airwhich accumulutes in the condenser, and which generally is expelled bythe action ot' an air-pump, is removed from our condenser by a currentof water impelled through a series ot' conieal pipes', E E', which aresituated in the interier of the condenser, as clearly shown in thedrawings..

The first or lowest pipe, E, which may be coniealor cylindrical, is'open at the bottom and top, and its bottom end is elevated a littleabove the bottom of the condenser, as clearly shown in Fig 1 of thedrawings, so that the condcnsing and condensed water accunulatingin saidcondcnser will readily close said tube at its lower end.

The tube E' is conieal and open at top and bottom. lts lower end issomewhat larger than the upper end of the tube E, and it extends somedistance beyond it, as clearly shown in Fig. 1, leaving an annularspace, u', through which air is sucked up by thecurrent. of waterpassing up through the lipes E E'.

The current of water in the pipes E E' is inpcllcd by steam orcompressed air admitted to the lowest pipe, E, through the pipe F, whichis provided in the interior of the' c0i1- denser with a stop-cock, b, asclearly shown in the drawings. The plug of this stop-cock connects by arod, o, with the float d, which, when the condeuscr is empty, rests outhe bottom and closes the stop-cock. Ifthe condensed and comlensingwater begins to accumulate in the condenser, the float rises, it opensthe plug of the stop-cock, and admits steam or compressed air to theexpeller E E', which stean or conpressed air, being deflectel npward,produces a partial vacuun within the tubes, so that the water whichcovers the bottom ot' the pipe E 'is caused to rise in the same and rushup through the expeller into the receiving-tanlc (l. In its coursethrough the pipes E l the water creates a* draft through the annularspace (t between the upper end of the pipe E and the upper end ot' thepipe E', and the air eontained in the comlenser is sucked in andexpelled with the water rushing up through the pipes E E'. i

This expeller starts ,and stops automatically by the action of the floatd, which opens the stop-cock b so soon as suflicient water hasaccumulated at the bottom of the condcnser to close the bottom end ofthe pipe E, and the i'js removed. from the condenser without. the 2.
